I have a 459 and I was unhappy with the DA trigger pull. It had a lot of heavy stacking. It would stack and then get light through the pull. I described it as a "hump", if that makes sense. I was on a quest to improve the trigger. I thought about the common fix, that would be polishing internal parts and a lighter hammer spring. I figured the lighter spring would make for a lighter pull weight, but not do much for the weird stacking. I also didn't think polishing parts would give me the results I wanted. I wanted the trigger to feel like the trigger in my CS9.
Sevens had an idea that putting 3rd gen mim parts into the gun might give me the results I was looking for. I found a complete set of frame parts from a model 910 on ebay for $80. I also bought an 18 lb hammer spring from wolff. I installed the 3rd gen hammer, trigger, drawbar, drawbar plunger and spring, and sear. I did not use the 910 disconnector because I prefer the metal disconnector. I did not use the levers from the 910 because the safety timing was a no go. I did not use the 910 hammer spring plunger because I prefer the metal one. The only parts I polished was the foot on the disconnector, hammer stirrup, and the inside of the hammer spring plunger.
The results are amazing. The difference is like night and day. The DA pull is totally smooth and consistant. The SA pull is great too. I am very happy with the results. It feels like the trigger in my CS9, but a little bit heavier. I have a theory that the CS9 came from the factory with a 16 lb or 17 lb hammer spring. Wondering if anyone can confirm which hammer spring the CS9 came with from the factory. Some people warn that too light of a hammer spring can cause light primer strikes, and others have said they use 16 lb and 17 lb springs on all types of 1st, 2nd, and 3rd gen and never had a light primer strike. I would be interested on opinions about this.
I also have installed a 3rd gen ambi safety/decocker on this 459. I call this gun "459 Generation 2.5". I know some might say, "why not just buy a 3rd gen gun, and not have to go through all this." I enjoy working on these guns to improve them. I also really like the model 459. I had one years ago, and it was one that I regret selling.
I've got a lot of great information from this forum. There are so many knowledgable and helpful members here. Thank you to Sevens for the great idea. Anyone else like the model 459? Show me yours.
